The invention discloses a new energy automobile battery positioning method and device, and relates to the technical field of computer vision. The method comprises the following steps: a new energy automobile battery positioning and mounting device is built; a manipulator grabs a battery to reach a shooting position for the first time and then shoots for the first time; a shot image is transmitted to a calibration tool through an interface to calibrate a camera; the calibrated image is subjected to training and image matching through a battery positioning identification model; matched coordinate parameters are positioned to determine the coordinates of point features; deviation calculation is performed on the point feature coordinates; and a deviation calculation result is fed back to the manipulator for calibration. According to the invention, the battery sampling image is obtained through the computer vision technology, the battery is positioned by using the battery positioning identification model, and the battery is rectified, positioned and installed according to the positioning data, so that manual operation is replaced, the battery replacement efficiency is improved, the battery replacement service process is simplified, and the service quality of the battery replacement station is improved.

    本发明公开了一种新能源汽车电池定位方法及装置,涉及计算机视觉技术领域。本发明包括如下步骤:搭建新能源汽车电池定位安装装置;机械手抓取电池第一次到达拍摄位置后进行第一次拍摄;拍摄的图像通过接口传送至标定工具进行相机的标定;将标定完成的图像进行电池定位识别模型进行训练和图像匹配;将匹配到的坐标参数进行定位确定点特征的坐标;对点特征坐标进行偏差计算;偏差计算结果反馈至机械手进行校准。本发明通过计算机视觉技术获取电池采样图像,利用电池定位识别模型对电池进行定位,并根据定位数据对电池进行纠偏定位安装,代替人工操作增加更换电池效率,简化换电服务流程,提高换电站的服务质量。
